PLEASE HELP - Open aud project, orphan all files opens blank

[Gale Andrews]

Here is the list 2 txt file

Here is "worldrecordpodcast2.aup" for "worldrecordpodcast2_data".

This one may not be so straightforward.

As you can imagine the 10240 start points for each waveblock In the AUP are now 1342177280 samples ahead of where they should be. I have not modified these values because some kind of automated function would be required to deduct 1342177280 from each "waveblock start" value. Does anyone know what type of tool or function might do this?

As it is now, I suggest you backup "worldrecordpodcast2_data" and try the attached with one copy of the data. On the basis of my tests there will be a sequence error on opening the project. Audacity is designed to correct this type of fault where blockfiles do not start at the correct place, and will offer to repair the problem. I suggest you let Audacity do the repair (it may take a long time) and see what happens.

If Audacity is only concerned with the numsamples of each channel being no more than 2 to the power of 31 (the 32-bit limit or 2147483648 samples) then I expect the repair to work and all should be well.

If Audacity gets confused by the AUP's current (incorrect) start point for the final block in each channel (2684092416 which is in excess of the maximum of 2147483648), then I imagine the project opening will fail in some way or the other.

Let us know what happens.

This seemed to work. Gave me an error of 8000+ orphaned files... It came out to a section of 5 hours and some minutes.... I am not sure if this is what it is supposed to be as the whole thing in 25:01 and the first aup project was a little over 8 hours but perhaps this is correct... I am in the process of piecing these two together to see if they line up. but it is definitely a step in the right direction. I look forward to 3!

No, not correct. I would not have expected any orphans and the length should be exactly the same as the first project (40 "d" folders are being recovered, as in the first project).

I assume the project is failing when the waveblock start value exceeds 2147483648 at about two-thirds through the project, which was always a possibility. If so, I could make a clean second project that had audio to that point (5.5 hours or whatever it is), but it won't be possible to make a final AUP using this method unless the waveblock start values can be changed. This has never been tried before, so no-one knows what will happen.

ok so what is the next move? Thank you for your attention!

[Gale Andrews]

What have you got so far? Have you verified you have a complete 5.5 hours or whatever from that second project and that it follows on from the first project correctly?

The second project had the same number of block files as the first one (10240). If Audacity saw 8000 orphans (are you sure you don't mean 2000?) this suggests the project could have gaps or be incorrect. In that case, it would be better to make a smaller second project that would open without error, assuming the waveblock start values cannot be autoreplaced. We're still looking into that.

I know the end point of the first is close to the start point of the second. I have not had time to check them exactly, have some issues here at the office, but I am open to whatever you think... I will check on the orphans number when I can... I'll try it with a new copy and take exact note... We are open to any ideas you have to piece it together...

4096 orphan files... Length is 5:06:41... thanks

[tylerstringer]

So the the end of the 1st audio file and the beginning of the second match up perfectly. It is a hard file to work with as it takes along time to do anything but it is working!

I would have expected it to fail later than that, where the start value exceeds 2^31.

Anyway, I attach a new version of worldrecordpodcast2.aup which I think will work correctly. Using a Windows PowerShell script that someone helped me with, all the waveblock start values have been changed to go from "0" to "1341915136" by increments of 262144 as they did in the first project.

This is for "worldrecordpodcast2_data" which contains e00/"d28" to "d4f" inclusive.

I also have a possible perl method I could try to figure out which would thus work on other than Windows XP SP2 and later which are required for PowerShell. This assumes earlier PowerShell versions can run the script I was using on PowerShell v3 Windows 7 SP1 - I don't know that yet.

No error messages and:

This one came out at 8:27:15! Awesome...

Can we try #3?


You are awesome!
